Coverage under the Insurance Services Office, Inc. (ISO), broad and special
causes of loss forms (CP 10 20 and CP 10 30) for collapse of a building and
(beginning with the 1995 editions) collapse of personal property within a building

coverage for collapse due to design error, or to collapse due to faulty workmanship
or materials if the collapse occurs after construction is complete.
